How to create a native (i.e. non CMD-dependent) application that uses MS-Terminal directly for its front-end (CLI) interface?

[Bleus]

Let me open by acknowledging that I am not a regular GitHub user, so please forgive me if this question illustrates a gross lack of understanding as to how to use this resource. As far as I can tell, it seems like everything here is predicated on compiling this application, whereas my interest is entirely focused on using it with my own applications.

To wit:

I currently have an old C# Class Library that co-opts legacy Windows CMD shells in order to emulate a clean, OS-agnostic, application-specific CLI shell. I would very much like to migrate / replace this older, bodged solution with a new implementation that can natively leverage this shell/terminal interface directly instead (i.e. without ever needing to invoke CMD). All I want is direct access to the interface facilities provided within Terminal for use by my own Windows-native applications whose user-interfaces are based on command-lines. I don't need or want to incur the totally unnecessary overhead of having to first instantiate and then commandeer a CMD session and then having to emulate an application-specific CLI from scratch over top of it (as the current implementation does).

Is there an existing, published, MS-Terminal API available for VisualStudio that I can simply attach as a resource to a new VS "Class Library" project to facilitate this? If so, how do I go about obtaining and implementing it?

Thanks!
